Lockheed Martin (NYSE: LMT) announced today that it has submitted its final proposal revision for the Ground-based Midcourse Defense (GMD) Development and Sustainment Contract. The Lockheed Martin-Raytheon GMD team delivered its final offer to the U.S. Missile Defense Agency's (MDA's) GMD Joint Program Office in Huntsville, Ala., Nov. 18.

The contract will provide development, manufacturing, test, training, performance-based logistics, operations and sustainment of the GMD element of the Ballistic Missile Defense System. The GMD element of the Ballistic Missile Defense System provides combatant commanders the capability to engage and destroy limited intermediate- and long-range ballistic missile threats in the midcourse battle space to protect the United States.

The Lockheed Martin-Raytheon team submitted its proposal in January and a proposal update in September.

"The entire Lockheed Martin-Raytheon team has worked together as partners in a transparent environment throughout the GMD Development and Sustainment Contract pursuit," said Mathew J. Joyce, GMD vice president and program manager, Lockheed Martin Space Systems Company. "As a result, our team delivered a thorough and comprehensive proposal that represents all of our capabilities. The Lockheed Martin-Raytheon team is committed to this mission, and we are continuing to work together to prepare for a robust start-up that will deliver an effective, affordable GMD program."

"Raytheon is proud of its role as the developer and producer of the Exoatmospheric Kill Vehicle," said Wes Kremer, Raytheon vice president of Air and Missile Defense Systems. "The Lockheed Martin-Raytheon team is well positioned to provide the nation with the right solution for defeating intermediate- and long-range ballistic missile threats."

Lockheed Martin will be the GMD prime contractor and systems integrator, leading the team's work at all major GMD sites: Huntsville, Ala.; Fort Greely, Alaska; Eareckson Air Station, Alaska; Schriever Air Force Base, Colo.; and Vandenberg Air Force Base, Calif. Strategic partner Raytheon will provide the GMD Exoatmospheric Kill Vehicle, as well as systems engineering, development, modeling and simulation, operations and sustainment, manufacturing, testing and training.

Strategic partners Lockheed Martin and Raytheon will apply their expertise in interceptor weapon systems to the GMD mission. Systems developed by Lockheed Martin and Raytheon have achieved more than 50 intercepts in testing and combat and include Terminal High Altitude Area Defense (THAAD), Aegis Ballistic Missile Defense with the Standard Missile-3 interceptor and Patriot with the Patriot Advanced Capability-3 interceptor. Accomplishments in 2011 have included the Oct. 5 THAAD initial operational test and evaluation that challenged the system to track, detect and intercept two different targets utilizing two THAAD interceptors, a first for the system. The team's credentials include: more than 30 years of experience in midcourse hit-to-kill missile defense development, production, testing, fielding and operations; more than 50 years of experience in strategic weapon system development, test, operations and sustainment and strategic weapon facility operations; and Department of Defense award-winning performance-based logistics expertise.
